Abstract: A high-speed vertical take-off and land (HSVTOL) aircraft comprises a disk-shaped body with a annular rotor having a rotatable fan assembly driven by redirected jet exhaust gases. The rotatable fan assembly includes fan blades, each with movable airfoil portions, and stationary flap portions with nozzles located on the trailing edges. Low pressure inflatable O-ring seals and bearings are positioned along a labyrinth interface between the disk-shaped body and the rotor. The rotatable fan assembly of the rotor is connected to an annular plenum receiving the hot exhaust gases. For vertical flight, substantially all of the hot exhaust gases of the turbojet engines are redirected into the plenum by main bypass and control bypass doors. Converging ducts located in the rotor just upstream of the rotatable fan assembly receive and direct the hot exhaust gases from the plenum to radially extending feed tubes connected to the nozzles.
